Workflow development system with ease-of-use features

ABSTRACT

A workflow development system is described that provides a developer with a search utility for finding steps for inclusion in a workflow. The system also automatically generates a meaningful name and/or graphical representation for a workflow. The system also provides a graphical user interface that represents output parameters of a first workflow step as user-interactive objects. These objects can be interacted with to cause the objects to be inserted into a data entry element that is used to specify a value for an input parameter of a second workflow step. When executable logic representing the first and second workflow steps is generated, the insertion of the objects into the data entry element has the effect of causing the value of the input parameter of the second workflow step to be defined to include the values of the output parameters that correspond to the inserted objects.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 62/258,851, filed on Nov. 23, 2015, the entirety of which is incorporated by reference herein.

BACKGROUND

A business or enterprise application is a computer program used by business users to perform various business functions. Business applications are frequently developed when available off-the-shelf software does not completely address the desired functionality. Many business applications are interactive, having a graphical user interface (GUI) via which users can input data, submit data queries, perform operations, and view results. Consumer applications are less business focused, instead being focused on the needs of the consumer.

Business and consumer users tend to depend on information technology (IT) personnel to code their applications due to application complexity, and the programming expertise required. For example, merely designing an application to retrieve data from a remote source (e.g., a cloud service) is difficult, typically requiring the involvement of an experienced software developer.

Developing business and consumer applications is an activity that is typically performed on desktop computer systems having relatively large displays and a standard keyboard and mouse for accepting user input. Consequently, many tools for developing business and consumer applications do not include GUIs that are designed to efficiently use whatever screen space is available for displaying the GUI. Likewise, many tools for developing business and consumer applications do not include GUIs that take advantage of touch-based user input schemes or other techniques for reducing the amount of user interaction and user input required to develop such applications.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Methods, systems, apparatuses, and computer program products are described herein that provide a developer or other user with a search utility for finding operations that can be included in a workflow currently being developed. The search utility can also be used by a developer or other user to find workflow templates or complete workflows.

Methods, systems, apparatuses, and computer program products are also described herein that automatically generate a meaningful name and/or graphical representation (e.g., an icon) for a workflow. The name and/or graphical representation may be generated, for example, based on steps included in the workflow and/or on one or more services that are referenced by the workflow.

Methods, systems, apparatuses, and computer program products are also described herein that provide a GUI for a workflow development system. The GUI represents output parameters of a first workflow step of a workflow under development as user-interactive objects. These objects can be easily interacted with (e.g., clicked on or dragged and dropped) by a developer to cause the objects to be inserted into a data entry element that is used to specify a value for an input parameter of a second workflow step of the workflow under development. When executable logic representing the first and second workflow steps is generated, the insertion of the objects into the data entry element has the effect of causing the value of the input parameter of the second workflow step to be defined to include the values of the output parameters that correspond to the inserted objects.

Further features and advantages of the invention, as well as the structure and operation of various embodiments, are described in detail below with reference to the accompanying drawings.

II. Example Embodiments for Development of Workflows

Business applications and consumer applications are typically created when available off-the-shelf software does not completely address the desired functionality. Many business and consumer applications are interactive, having a GUI via which users can input data, submit data queries, perform operations, and view results.

Users tend to depend on IT personnel to code their applications due to application complexity and the programming expertise required. For instance, configuring an application to retrieve data from a source of interest to enterprises or consumers (e.g., data from an SQL (structured query language) database, customer relationship information from Salesforce.com of San Francisco, Calif., social network information from Facebook® operated by Facebook, Inc. of Palo Alto, Calif., or Twitter® operated by Twitter, Inc. of San Francisco, Calif.) is a difficult process.

Embodiments described herein enable easier development of applications, including business applications and consumer applications. Users are enabled to develop applications in the form of workflows without having to be expert programmers.

Example embodiments are described in the following subsections for development of applications in the form of workflows. In the following description, a person that develops an application using the techniques described herein is referred to as a “developer,” to be distinguished from a person that uses the application at runtime (a “user” or “end user”). It is noted, however, that a “developer,” as referred to herein, does not need to have any expertise in computer programming. Various embodiments described herein enable application development without special programming skills.

A. Example Workflow Development Embodiments

Development of workflows may be enabled in various ways in embodiments. For instance, FIG. 1 is a block diagram of a workflow development system 100, according to an example embodiment. As shown in FIG. 1, system 100 includes a computing device 102, storage 104, a first network-based application 124A, a second network-based application 124B, and a server 134. Server 134 includes a workflow designer 106 and a workflow library 118 (e.g., in storage). Computing device 102 includes a display screen 108 and a browser 136. Storage 104 stores a local application 122. System 100 is described as follows.

Computing device 102 may be any type computing device, including a mobile computing device (e.g., a smart phone, a Microsoft® Surface® device, a laptop computer, a notebook computer, a tablet computer such as an Apple iPad™, a netbook, etc.), a wearable computing device (e.g., a head-mounted device including smart glasses such as Google® Glass™, etc.), or a stationary computing device such as a desktop computer or PC (personal computer). Server 134 may include one or more server devices and/or other computing devices.

Local application 122 in storage 104 is an example of an application accessible by computing device 102 without communicating over a network. Local application 122 may be configured to perform data processing and/or data hosting operations when executed by a processor of computing device 102, and may provide data 132 to workflows developed using workflow designer 106 when such workflows are executed at runtime. Local application 122 may be any type of local application or service, such as a database application (e.g., QuickBooks®, a Microsoft® Excel® spreadsheet), an e-mail application (e.g., Microsoft® Outlook®), a productivity application (e.g., Microsoft® Word®, Microsoft® PowerPoint®, etc.), or another type of application. Although FIG. 1 shows a single local application, any number of local applications may be present at computing device 102, including numbers in the tens, hundreds, or greater numbers.

First and second network-based applications 124A and 124B are examples of network-based applications, which in some instances may be referred to as “cloud” applications or services. Network-based applications 124A and 124B are accessible by computing device 102 over network 126, may be configured to perform data processing and/or data hosting operations, and may provide data 130A and 130B, respectively, to workflows created using workflow designer 106 when such workflows are executed at runtime. Network-based applications 124A and 124B may each be any type of network-accessible applications or services, such as database applications, social networking applications, messaging applications, financial services applications, news applications, search applications, productivity applications, cloud storage applications, file hosting applications, etc. Examples of such applications include a network-accessible SQL (structured query language) database, Salesforce.com™, Facebook®, Twitter®, Instagram®, Yammer®, LinkedIn®, Yahoo!® Finance, The New York Times® (at www.nytimes.com), Google search, Microsoft® Bing, Google Docs™, Microsoft® Office 365, Dropbox™, etc. Although FIG. 1 shows two network-based applications, any number of network-based applications may be accessible over network 126, including numbers in the tens, hundreds, thousands, or greater numbers.

Note that data 130A, data 130B, and data 132 may each include any type of data, including messages, notifications, calculated data, retrieved data, structured data, unstructured data, and/or any other type of information requested or usable by a workflow.

Computing device 102 and server 134 may each include at least one wired or wireless network interface that enables communications with each other and with network-based applications 124A and 124B over network 126. Examples of such a network interface include an IEEE 802.11 wireless LAN (WLAN) wireless interface, a Worldwide Interoperability for Microwave Access (Wi-MAX) interface, an Ethernet interface, a Universal Serial Bus (USB) interface, a cellular network interface, a Bluetooth™ interface, a near field communication (NFC) interface, etc. Further examples of network interfaces are described elsewhere herein. Examples of network 126 include a local area network (LAN), a wide area network (WAN) such as the Internet, a personal area network (PAN), and/or a combination of communication networks.

Workflow designer 106 is configured to be operated/interacted with to create applications in the form of workflows. For instance, a developer may access workflow designer 106 by interacting with an application at computing device 102 that is capable of accessing a network-based application, such as browser 136. The developer may use browser 136 to traverse a network address (e.g., a uniform resource locator) to workflow designer 106, which invokes a workflow designer GUI 116 (e.g., a web page) in a browser window 114. The developer is enabled to interact with workflow designer GUI 116 to develop a workflow.

As shown in FIG. 1, workflow designer 106 includes a UI generator 110 and a workflow logic generator 112. UI generator 110 is configured to transmit workflow GUI information 140 (e.g., one or more web pages, image content, etc.) to browser 136 to be displayed as workflow designer GUI 116 within browser window 114 in display screen 108. Workflow designer GUI 116 may be interacted with by a developer to select and configure workflow steps into a workflow. For example, the developer may insert and sequence a plurality of workflow steps in workflow designer GUI 116, with one or more of the steps being associated with a local or network-based application. Browser 136 stores the selected workflow steps, corresponding configuration information, and workflow step sequence information as constructed workflow information 138. Constructed workflow information 138 is transmitted to workflow logic generator 112 at server 134. Workflow logic generator 112 generates workflow logic 120 based on the assembled workflow represented by constructed workflow information 138. The workflow represented by workflow logic 120 may subsequently be invoked for execution by an end user.

During runtime execution of the workflow, workflow logic 120 may invoke operation of one or more local or network-based applications associated with the workflow steps of workflow logic 120. Each workflow step may receive input data. Such input data may include, for example, data 132 from local application 122, data 130A from network-based application 124A, data 130B from network-based application 124B, data from another application, and/or data from another workflow step of workflow logic 120.

Workflow designer 106 may operate in various ways, to enable development of a workflow. For instance, in embodiments, workflow designer 106 may operate in accordance with flowchart 200 of FIG. 2. In particular, flowchart 200 depicts a process for development of workflows, according to an example embodiment. Flowchart 200 and workflow designer 106 are described as follows with respect to FIGS. 3 and 4. FIG. 3 is a block diagram of workflow designer 106, according to an example embodiment. As shown in FIG. 3, workflow designer 106 includes UI generator 110 and workflow logic generator 112. UI generator 110 includes a template gallery generator 302, a saved workflow selector 304, a step selector 306, and a step configuration UI generator 308. Workflow logic generator 112 includes a workflow definition generator 312 and an interface definition generator 314. FIG. 4 is a block diagram of display screen 108, illustrating an example of workflow designer GUI 116 displayed in browser window 402 on display screen 108, according to an example embodiment

Flowchart 200 of FIG. 2 begins with step 202. In step 202, development of a workflow is initiated. For example, in an embodiment, workflow designer 106 may be invoked by a developer interacting with browser 136 at computing device 102. The developer may traverse a link or other network address directed to workflow designer 106 at server 134, to invoke workflow designer 106, causing workflow designer 106 to provide workflow GUI information 140 (e.g., one or more web pages, image content, etc.) to browser 136 to be displayed as workflow designer GUI 116 in display screen 108 in browser window 114. Once invoked, the developer may open an existing workflow for further development, or may begin developing a new workflow.

In one example, a displayed page of workflow designer GUI 116 may display a template gallery generated by template gallery generator 302. The template gallery may include a plurality of selectable workflow templates, each of which includes one or more pre-selected workflow steps that are suitable for further configuration by a developer. The workflow templates may be stored in workflow library 118, and accessed for display by workflow designer GUI 116. The developer may select one of the workflow templates for inclusion in their workflow, and may proceed with configuring the contents of the workflow template, and/or may add additional workflow steps to the workflow steps of the workflow template to generate a more complex workflow.

For instance, in the example of FIG. 4, steps 406A and 406B may have been included in a workflow template placed in workflow 404, and step 406C may have been subsequently added (e.g., via selection from a menu or other list of workflow steps).

In another example, saved workflow selector 304 may enable the developer to select an existing, saved workflow to be opened for further editing in a displayed page of workflow designer GUI 116. The saved workflows may be stored in workflow library 118 or elsewhere. For example, saved workflow selector 306 may display a list of saved workflows, may enable navigation to a saved workflow, and/or may provide another mechanism for selecting a saved workflow for editing. The developer may then proceed with further configuring the contents of the workflow, adding workflow steps, modifying workflow steps, removing workflow steps, or the like.

In yet another example, a displayed page of workflow designer GUI 116 may provide a blank window, area or canvas to which one or more developer-selected workflow steps may be added, ordered and configured. Such blank window, area or canvas may be generated by UI generator 110 automatically or in response to some developer input or interaction.

In step 204, selection of one or more steps for inclusion in the workflow is enabled. When a developer is editing a workflow, step selector 306 may enable the developer to select workflow steps for inclusion in the workflow, and to order the steps. The workflow steps may be accessed by step selector 306 in workflow library 118. For instance, step selector 306 may display a menu of workflow steps, a scrollable and/or searchable list of available workflow steps, or may provide the workflow steps in another manner, and may enable the developer to select any number of workflow steps from the list for inclusion in the workflow.

In one example, step selector 306 may enable a developer to select a step that is associated with a local application, such as Microsoft® Outlook®, or a network-based application, such as Facebook®. Step selector 306 enables the steps to be chained together in a sequence, optionally with conditional steps, for inclusion in workflow logic 120.

In step 206, each of the selected steps in the workflow is enabled to be configured. In an embodiment, step configuration UI generator 308 enables configuration of each workflow step in a workflow. Step configuration UI generator 308 accesses each selected workflow step in workflow library 118 to determine the configuration of the workflow step, including all of its input parameters and any other selections or information that a developer needs to provide to the workflow step to configure it. For example, step configuration UI generator 308 may generate a UI that enables the developer to type, navigate to, use a pull-down menu, or otherwise enter input data into a text input box or other data entry element to configure (e.g., specify an input parameter of) a workflow step. The developer may configure an output parameter of a prior step to be input data for a workflow step. Step configuration UI generator 208 may enable data or other objects to be copied and pasted, dragged and dropped, or otherwise entered from elsewhere into data entry elements of a workflow step.

In step 208, workflow logic to implement the workflow is generated. In an embodiment, workflow logic generator 112 is configured to package and generate workflow logic 120 based on constructed workflow information 138 when the developer indicates the workflow is finished, such as when the developer interacts with workflow designer GUI 116 to save the workflow. As shown in FIG. 3, workflow logic generator 112 receives constructed workflow information 138. Constructed workflow information 138 indicates which workflow steps have been inserted into the workflow, their input parameter values, and their sequencing. Workflow logic generator 112 also receives selected workflow logic 320, which is the workflow logic for each workflow step of the workflow as indicated in constructed workflow information 138. In one example, workflow logic generator 112 retrieves workflow logic from workflow library 118 for each workflow step indicated in constructed workflow information 138, to receive selected workflow logic 320. Workflow logic generator 112 generates workflow logic 120 for the workflow based on constructed workflow information 138 and selected workflow logic 320. For example, workflow logic generator 112 may generate workflow logic 120 in the form of an executable file, a zip file, or other form, which may be executed in a standalone fashion, may be executed in a browser, or may be executed in another manner, depending on the particular type of workflow being generated.

With reference to FIG. 3, workflow logic generator 112 may generate workflow logic 120 to include at least two components (e.g., files): workflow definition information 316 and interface definition information 318. Workflow definition information 316 includes information that defines the sequence and operation of the workflow of workflow logic (e.g., lists the workflow step operations and their ordering/sequencing) and includes the parameter values for the workflow. For example, workflow definition information 316 may be generated to contain information in the format of a JSON (JavaScript object notation) file or in another form. Interface definition information 318 includes information that defines the interfaces/parameters (e.g., inputs and outputs) of the workflow steps of the workflow. For example, interface definition information 318 may be generated to contain information in the format of a Swagger (a specification for REST (representational state transfer) web services) file or in another form. For instance, each workflow step may be represented in workflow library 118 as API (application programming interface) metadata in Swagger format, defining what are the inputs and outputs (parameters) of the workflow step, such that a service may be accessed according to the API definition. In such an implementation, the operations in the workflow definition information 316 refer to the corresponding API metadata in the interface definition information 318 to provide a complete structure of a generated workflow (e.g., each sequenced workflow step/operation defined with parameter values in the workflow definition information 316 has a corresponding API, which is defined in the interface definition information 318).

Accordingly, flowchart 200 and workflow designer 106 enable a developer to create workflows. FIGS. 5-8 show views of an exemplary workflow in various phases of development using a workflow designer GUI, according to example embodiments. For example, each of FIGS. 5-8 shows browser window 402 displaying a corresponding view of workflow designer GUI 116 being used to develop a workflow.

For instance, FIG. 5 shows browser window 402 including a workflow step 502 and an add interface 504. Workflow step 502 was selected by a developer to be a first step in a workflow. Add interface 504 (e.g., a button or other GUI control) may be interacted with by the developer to add further workflow steps to the workflow.

As described above, a developer is enabled to select workflow step 502 from a list or library of steps, a template gallery, or elsewhere. A list, library, or gallery may include any number of workflow steps. The workflow steps may be associated with network-based applications mentioned elsewhere herein or otherwise known (e.g., Dropbox™), and/or with local applications mentioned elsewhere herein or otherwise known (e.g., Microsoft® Outlook®). Each workflow step is configured to be plugged into the workflow. Each workflow step is configured with the appropriate logic and/or interface(s) to perform its respective function(s), which may include communicating with a local or remote application. For instance, a workflow step for transmitting a query to an application (e.g., a search query to a search engine, a database query to a database, a request for data from a social networking application, etc.) may be pre-configured in terms of how to properly transmit and format such a request to the application. As another example, a workflow step for receiving a response to a request may be pre-configured in terms of how to parse the response for desired response data. As such, a developer of a workflow does not need to know how to write program code in a programming language, to interface with complex application interfaces (e.g., application programming interfaces (APIs)), or to understand network communication protocols, as the workflow steps are already set up. When a workflow step is plugged into workflow logic by a developer, the developer configures the inputs to the workflow step (as described below), and the pre-configured workflow step handles any communications with other applications.

In FIG. 6, the developer has interacted with step 502 (e.g., by mouse click, etc.) to cause step configuration UI generator 310 to generate a UI for configuration of step 502. For instance, in the example of FIG. 6, workflow step 502 is configured to perform monitoring to determine if a file has been created in a particular folder identified by the developer in a text input box (e.g., by typing, clicking on a navigator indicated by “ . . . ”, etc.). When workflow step 502 determines that a file has been added to the indicated folder, a workflow step following workflow step 502 is triggered. Thus, workflow step 502 may be considered a trigger step in this example.

For instance, in FIG. 7, the developer interacted with add interface 504 to facilitate the selection of a next workflow step 702. For instance, in an embodiment, interaction with add interface 502 invokes step selector 306 in FIG. 3, which enables the developer to select a workflow step. In the example of FIG. 7, workflow step 702 is a conditional step. In embodiments, logical elements may be selected for inclusion in a workflow, including arithmetic logic (e.g., summers, multipliers, etc.), conditional logic, etc., that operate based on variable values determined in earlier workflow steps. The condition of workflow step 702 enables the workflow to fork based on the determination of a condition (e.g., a variable value). The condition may include an object name, a relationship (e.g., a logical relationship, such as equal to, includes, not equal to, less than, greater than, etc.), and a value, which are all defined by the developer interacting with workflow step 702. Corresponding action steps may be performed depending on which way the workflow forks based on the condition.

For instance, in one illustrative example of FIG. 7, the object name may be selected (e.g., from a list of possibilities) to be a name of the created file of workflow step 502, the relationship may be “contains” (e.g., selected by a pull-down menu) and the value may be “dummyfile” (e.g., typed in by the developer). The condition evaluates to a “yes” condition if the file name contains “dummyfile,” which invokes first action workflow step 704, and evaluates to “no” condition if the file name does not contain “dummyfile,” which invokes second action workflow step 706. An action may be defined for one or both of the “yes” and “no” action workflow steps 704 and 706 by the developer, if desired.

For example, in FIG. 8, the developer interacts with action workflow step 704 to define an action. In this example, the developer is defining action workflow step 704 by selecting a workflow step via step selector 306. As shown in FIG. 8, a list of workflow steps 802A, 802B, 802C is displayed, from which the developer can select a workflow step (e.g., by mouse click, etc.) to be performed for action workflow step 704. The workflow step can be a trigger step, an action step, or a condition step. After selecting the workflow step, the developer may configure the workflow step as described above. Furthermore, the developer may configure an action for workflow step 706, may add further workflow steps, etc., eventually being enabled to save the workflow.

It is noted that in some embodiments, a workflow step, such as first workflow step 502, may require credentials (e.g., a login and password) to access indicated data (e.g., to access a file at the location indicated in the text input box in FIG. 6). As such, the developer may be requested to provide credential information in association with first workflow step 502 so that when first workflow step 502 is performed during runtime, the data may be accessed. Alternatively, the credentials may be requested of a user during runtime.

B. Example Runtime Embodiments

According to embodiments, end users may execute workflows developed as described herein. During operation, an end user may interact with a GUI of the workflow, which may lead to workflow logic being executed. The workflow logic may execute locally (e.g., in a browser) and/or at a remote service (in “the cloud”). The workflow logic may access data of one or more local or network-accessible applications as was configured by the developer. Accordingly, the workflow performs its intended functions.

FIG. 9 is a block diagram of a system 900 for executing a workflow that includes one or more workflow steps, according to an example embodiment. As shown in FIG. 9, system 900 includes a computing device 902, first network-based application 124A, second network-based application 124B, and server 134. Computing device 902 includes a workflow application 904. Server 134 includes a workflow execution engine 906. System 900 is described as follows.

First and second network-based applications 124A and 124B are each optionally present, and whether or not such applications are communicated with will depend on the configuration of workflow logic 120. Further network-based applications may be present and communicated with, depending on the configuration of workflow logic 120.

Computing device 902 may be any type of stationary or mobile computing device described herein or otherwise known. Computing device 902 is configured to communicate with first and second network-based applications 124A and 124B and server 134 over network 126.

In one embodiment, workflows are executed at server 134 by workflow execution engine 906, and workflow application 904 is a UI application that enables a user at computing device 902 to interact with the executing workflows, such as by selecting and invoking the workflows, receiving communications from the executing workflows (e.g., messages, alerts, output data, etc.), providing requested input data to executing workflows, etc. In such an embodiment, workflow application 904 may be a workflow UI application associated with workflow execution engine 906 (e.g., workflow application 904 may be an extension of workflow execution engine 906) that may operate separate from or within a browser at computing device 902, or may be configured in another way. As shown in FIG. 9, workflow execution engine 906 may load workflow logic 120 for a selected workflow (e.g., selected from a workflow library by a user), and may execute workflow logic 120 to execute the workflow.

In another embodiment, workflow application 904 may be configured to execute workflows at computing device 902. For instance, an end user of computing device 902 may interact with a user interface of workflow application 904 to select and invoke a particular workflow (e.g., selected from a workflow library). In such embodiments, workflow logic 120 may operate separate from or in a browser at computing device 902, or may be configured in another way. As shown in FIG. 9, workflow application 904 may load workflow logic 120 for a selected workflow (e.g., selected from a workflow library by a user), and may execute workflow logic 120 to execute the workflow.

In another embodiment, a first portion of workflow logic 120 may execute in workflow application 904 at computing device 902 and a second portion of workflow logic 120 may execute in workflow execution engine 906 at server 134 and/or elsewhere.

FIG. 10 depicts a flowchart 1000 of a process for executing workflow logic 120 of a workflow, according to an example embodiment. Flowchart 1000 is described as follows with respect to system 900 of FIG. 9 for illustrative purposes.

Flowchart 1000 begins with step 1002. In step 1002, the workflow is executed. In an embodiment, an end user at computing device 902 may cause workflow logic 120 to be executed, such as by command line, by clicking/tapping or otherwise interacting with an icon representing the application, by selection in a browser, or in another manner. As described above, workflow logic 120 may execute in workflow application 904 at computing device 902 and/or in workflow execution engine 906 at server 134. When executed, the workflow steps of workflow logic 120 are performed in the configured sequence. Accordingly, one or more of the workflow steps may make calls to corresponding applications/services to perform their functions, such as local application 122 (to return data 132), network-based application 124A (to return data 130A), network-based application 124B (to return data 130B), and/or other local or network-based applications.

In step 1004, the workflow GUI is displayed. Step 1004 is optional, as in some embodiments, a GUI is not displayed for a workflow. In an embodiment, the GUI may be displayed by workflow application 904 at computing device 902. When displayed, the user may interact with the GUI by reviewing displayed data (e.g., from a file, database record, spreadsheet, or other data structure read by the workflow), by entering data into the GUI (e.g., by typing, by voice, etc.), and/or by interacting with one or more controls displayed by the GUI.

In step 1006, workflow logic is triggered based on an interaction with the workflow. Step 1006 is optional in cases where one or more workflow steps of a workflow require input from a user. In such cases, the user interacts with a control in a GUI of workflow application 904 associated with a workflow step of workflow logic 120 to provide information that triggers logic of the workflow step to operate.

In this manner, workflow logic 120 performs its functions, such as processing orders, tracking information, generating messages, processing documents to generate tasks or information, collecting feedback, and/or any other functions.

C. Example Embodiments for Workflow Development that Incorporate a Search Engine

As discussed above, in certain embodiments, step selector 306 of UI generator 110 may be invoked to present a developer with a list of steps, each of which may be selected for insertion into a workflow under development. In an embodiment that will now be described, step selector 306 is configured to provide the developer with a means for interacting with a search engine that can be used to identify workflow steps of interest to the developer. This enables the developer to quickly find useful and suitable workflow steps for developing her workflow. Furthermore, in embodiments, step selector 306 may be configured to provide a developer with access to this functionality within the context of a workflow designer GUI that concurrently displays a representation of the workflow currently being developed. Consequently, a developer can identify relevant workflow steps precisely when she needs them and without having to navigate away from the workflow representation.

FIG. 11 is a block diagram of server 134 that includes workflow designer 106 and workflow library 118 (as previously discussed above in reference to FIG. 1). As shown in FIG. 11, workflow designer 106 also includes a search engine 1102. As will be discussed below in reference to FIG. 12, workflow designer 106 utilizes search engine 1102 to present a developer with a set of workflow steps for insertion into a workflow under development.

In particular, FIG. 12 depicts a flowchart 1200 of a method performed by workflow designer 106 for searching for and presenting a developer with a set of workflow steps for insertion into a workflow under development. As shown in FIG. 12, the method of flowchart 1200 begins at step 1202, in which input is accepted from a developer and is passed as a query to a search engine. This step may be performed, for example, by step selector 306, which receives input from a developer (e.g., text input by a developer) and passes the input as a query 1106 to search engine 1102. For example, step selector 306 may provide a data entry element (e.g. a text input box) or other interactive GUI component via which a user can provide input. Step selector 306 may present the data entry element within a workflow designer GUI that displays a representation of the workflow currently being developed.

At step 1204, the query is processed in a search engine to select one or more workflow steps from a library of workflow steps. This step may be performed, for example, by search engine 1102 which receives query 1106 and processes it to select one or more workflow steps from workflow library 118. In an embodiment, search engine 1102 selects the workflow step(s) by analyzing workflow step metadata 1104 associated with each of the workflow steps stored in workflow library 118 to identify workflow steps that are relevant to query 1106.

Workflow step metadata 1104 may include any type of structured or unstructured data concerning a workflow step. For example, such metadata may include a name or other identifier of the workflow step, a description of the workflow step, an identifier and/or description of a service that is utilized or referenced by the workflow step (e.g., Dropbox™, Facebook®, Outlook®, or the like), a description and/or identifier of a trigger monitored for by the workflow step, or a description and/or identifier of an action performed by the workflow step. The metadata may include multiple terms that can be used to describe the same step, service, trigger, or action so as to enable matching against a diverse array of developer queries.

In one embodiment, search engine 1102 comprises a natural language search engine that is configured to use natural language processing to interpret queries expressed using normal terms in a user's language, without any special syntax or format. For example, a natural language query may be expressed as a statement or a question. Such a natural language search engine may be capable of determining a user's intent based on the content of the query and provide highly-relevant workflow step suggestions. Of course, this is example is not intended to be limiting, and search engine 1102 may be configured to perform keyword searching, semantic searching, or any other type of searching known to persons skilled in the relevant art(s).

At step 1206, the search engine provides an identifier of each of the workflow steps selected during step 1204. This step may be performed, for example, by search engine 1102, which provides workflow step identifiers 1108 to step selector 306. In one embodiment, the identifiers comprise names of the selected workflow steps.

At step 1208, each of the identifiers provided during step 1206 is presented to the developer and the developer is enabled to select any one of them. This step may entail, for example, step selector 306 presenting the identifiers to the developer in a menu that is displayed within a workflow designer GUI that displays a representation of the workflow currently being developed. The developer may be enabled to navigate or scroll up and down the menu to highlight and select a particular workflow step.

At step 1210, upon selection of one of the identifiers by the developer, a representation of the workflow step corresponding to the selected identifier is rendered as part of a workflow under development that is currently being displayed in the workflow designer GUI. This step may be performed, for example, by step selector 306, when the developer selects a particular workflow step identifier from the aforementioned menu.

The foregoing technique will now be further illustrated with reference to example workflow designer GUIs of FIGS. 13-15. In particular, FIGS. 13-15 show different views of workflow designer GUI 116 displayed within browser window 402 of display screen 108 in an embodiment in which computing device 102 is a mobile computing device, such as a smart phone.

In FIG. 13, workflow designer GUI 116 comprises a “New flow” screen that enables a developer to build a new workflow without starting from a template or saved workflow (i.e., from scratch). This screen includes features that enable the developer to generate or identify a trigger step that will initiate the workflow. The trigger step may be thought of as a workflow step that monitors for the occurrence of a particular event and, when it determines that the particular event has occurred, triggers the execution of subsequent steps of the workflow.

As further shown in FIG. 13, workflow designer GUI 116 includes a menu 1304 of selectable trigger steps such as “Dropbox—When new file is uploaded,” “Dropbox—When new folder is created,” “Facebook—When I upload a photo,” “Facebook—When I upload a post,” “Facebook—When someone comments on my post,” “Outlook—When I send an email” and “Outlook—When I receive an email.” A developer may interact with (point and click with a mouse, touch via a touch screen, etc.) any of these example trigger steps to select it as the initial step in the workflow.

Alternatively, the developer may type text into a data entry element 1302 (in this case, a text box) that appears in workflow designer GUI 116 and includes the text “Start typing your first step . . . ”. The text that is input by the developer is provided as a query to search engine 1102 and used to find workflow steps that can be included in the workflow currently being developed. In this case, since only a trigger step is needed to start the automated workflow, search engine 1102 may only search for workflow steps that qualify as trigger steps. For subsequent steps of the workflow, a broader set of operations may be searched.

FIG. 14 shows workflow designer GUI 116 after a developer has entered the text “new file” into data entry element 1302. This text is provided as a query to search engine 1102. Based on the query, search engine 1102 selects a set of workflow steps (in this case, trigger steps) that are relevant to the query. Search engine 1102 returns identifiers of the selected workflow steps (in this case, icons and names) and such identifiers are displayed in a menu 1404. As shown in FIG. 14, the selected steps include “Box—When a file is created,” “Dropbox—When a file is created,” “OneDrive—When a file is crated,” “OneDrive for Business—When a file is created,” and “SharePoint Online—When a file is created.” A developer may interact with any of these example trigger steps to select it as the initial step in the workflow.

Once the developer has provided the information for the trigger step, the developer can then initiate the addition of a second step to the workflow. This feature is illustrated by FIG. 15. In particular, as shown in FIG. 15, after the developer has added the trigger step, the developer can add another step (e.g., an action or condition). It will be assumed for the sake of this example that the developer selected an action as the second step of the workflow. When the developer selects an action as the next step, the developer is presented with a menu 1504 of selectable trigger and action steps, as well as a data entry element 1502 that includes the text “What would you like to do next?” The developer may type text into data entry element 1502 and such text will be provided as a query to search engine 1102 and used to find workflow steps that can follow the trigger step in the workflow currently being developed. In this way, the developer may be presented with access to the search engine functionality each time the developer wants to add a new step to the workflow. Such functionality is advantageously presented within the same workflow designer GUI 116 used to display the workflow under development, which means that the developer need not navigate away from the workflow under development to perform the search.

Although in FIGS. 13-15, a text box is shown as being the means for providing input to search engine 1102, in an alternate embodiment, the input can be provided by speaking into a microphone. Such voice-based input may then be submitted to an entity executing on server 134 (or on a computing device that is communicatively connected thereto) that converts the voice-based input to text. The text returned by this entity may then be submitted to search engine 1102. In this way, voice-based natural language searching may be achieved.

As was discussed above, search engine 1102 operates by analyzing metadata associated with various workflow steps stored in workflow library 118 to identify workflow steps that are relevant to a developer query. In one embodiment, the metadata associated with a particular workflow step may be input by another developer. For example, workflow development system 100 may provide a GUI via which a developer can input metadata that is to be associated with one or more operations. In one particular embodiment, the developer provides the metadata at the time the developer registers an API for use with one or more workflows, as part of the API registration process. The API may be, for example and without limitation, an API for an online service that can be utilized or referenced by a step in an automated workflow.

In another embodiment, the metadata associated with a particular workflow step may be provided by multiple developers. For example, workflow development system 100 may provide a GUI by which multiple developers can voluntarily “tag” (e.g., provide descriptive terms for) the various workflow steps that can be included in a workflow. This enables a “crowd-sourcing” approach to generating the metadata that can then be used to facilitate the search functionality.

In a further embodiment, the techniques described above for identifying relevant workflow steps can be adapted such that they can be used by a developer to find workflow templates or saved workflows. For example, text or other user input provided by a developer via workflow designer GUI 116 can be provided as a query to a search engine. The search engine may analyze metadata associated with workflow templates or saved workflows to select workflow templates or saved workflows that are relevant to the query. Access to the selected workflow templates or saved workflows may then be provided to the developer, e.g., via the same workflow designer GUI 116.

D. Example Embodiments for Automatic Generation of Names and Graphical Representations of Workflows

In accordance with certain embodiments, workflow development system 100 is configured to automatically generate a name and/or graphical representation (e.g., an icon) for a workflow. The name and/or graphical representation may be generated, for example, based on steps included in the workflow and/or on one or more services that are referenced by the workflow. This feature advantageously enables a developer to assign a recognizable and meaningful name and graphical representation to a workflow without having to devise such name or graphical representation and without having to manually input the name or graphical representation into the system. An embodiment that incorporates this functionality will now be described.

FIG. 16 is a block diagram of server 134 that includes workflow designer 106 and workflow library 118 (as previously discussed above in reference to FIG. 1). As shown in FIG. 16, workflow designer 106 includes UI generator 110, workflow logic generator 112 and a workflow name and icon generator 1602. As will be discussed below in reference to FIG. 17, workflow name and icon generator 1602 is configured to automatically generate a name and graphical representation for a workflow.

In particular, FIG. 17 depicts a flowchart 1700 of a method for automatically generating a name and graphical representation for a workflow. As shown in FIG. 17, the method of flowchart 1700 begins at step 1702, in which constructed workflow information about a workflow is received. This step may be performed, for example, by workflow name and icon generator 1602, which (as shown in FIG. 16) receives constructed workflow information 138 from browser 136 executing on computing device 102. As was previously discussed in reference to FIG. 1, constructed workflow information 138 comprises the selected workflow steps, corresponding configuration information, and workflow step sequence information for a workflow currently being developed on computing device 102. Such constructed workflow information 138 is sent to workflow logic generator 112 to facilitate the generation of workflow logic 120 in a manner previously described. In this embodiment, constructed workflow information 138 is also provided to workflow name and icon generator 1602.

At step 1704, a name and/or graphical representation is automatically determined for the workflow based at least on the constructed workflow information. This step may be performed, for example by workflow name and icon generator 1602, which automatically generates a name and/or graphical representation 1604 for the workflow currently being developed on computing device 102 based at least on the constructed workflow information received during step 1702. For example, workflow name and icon generator 1602 may generate name and/or graphical representation 1604 of the workflow currently being developed based on one or more of: one or more steps included in the workflow (and the order thereof), one or more services that are referenced by the workflow (and the order in which such services are referenced), one or more trigger events that are monitored for by the workflow, one or more conditions included in the workflow, one or more actions included in the workflow, or the like. With respect to generating a workflow name, words that describe or relate to these aspects of the workflow may be combined to generate a suitable name for the workflow. With respect to generating a graphical representation, images that describe or relate to these aspects of the workflow may be combined to generate a suitable graphical representation for the workflow. For example, in one embodiment, a graphical representation for a workflow may be generated by combining icons associated with one or more steps included in the workflow and/or services referenced or interacted with by the workflow.

At step 1706, the name and/or graphical representation that was generated for the workflow is stored in association with the workflow. This step may be performed, for example, by workflow name and icon generator 1602 which may store name and/or graphical representation 1604 that was generated for a workflow in association with that workflow in workflow library 118.

At step 1708, the name and/or graphical representation that was generated for the workflow is provided for display within a workflow designer GUI. This step may be performed, for example, by workflow name and icon generator 1602 which may provide name and/or graphical representation 1604 to UI generator 110 so that UI generator 110 can pass name and/or graphical representation 1604 to browser 136 as part of workflow GUI information 140. Browser 136 may cause name and/or graphical representation 1604 to be displayed within workflow designer GUI 116 within browser window 114. For example, the automatically-generated name of the workflow may be displayed as a default workflow name within a text box or other data entry element that is used to enter names for workflows, such that a developer can either accept the name or overwrite it with a new one. As another example, the automatically-generated name and graphical representation may be displayed within a menu of saved workflows that a developer may interact within in order to activate, deactivate, edit, delete or perform other operations with respect to one or more of the saved workflows.

The foregoing technique will now be further illustrated with reference to example workflow designer GUIs of FIGS. 18 and 19. In particular, FIGS. 18 and 19 show views of a workflow designer GUI 116 displayed within browser window 402 of display screen 108 in an embodiment in which computing device 102 is a mobile computing device, such as a smart phone.

In FIG. 18, workflow designer GUI 116 displays a workflow 1802 that a developer has recently constructed using techniques that were described previously herein. As shown in FIG. 18, workflow designer GUI 116 also includes a save workflow dialog box 1804. Save workflow dialog box 1804 includes a data entry element 1806 (in this case, a text box) into which a developer may enter a name for the newly-constructed workflow as well as an activation button 1808 (labelled “OK”) that will cause the newly-constructed workflow to be saved with the name entered into data entry element 1806.

In an embodiment, UI generator 110 may cause data entry element 1806 to be pre-populated with a system-generated name for workflow 1802, wherein the system-generated name is generated using the method of flowchart 1700 as described above. Thus, as shown in FIG. 18, the system-generated name for workflow 1802 may be “When new folder is created send email.” However, this is merely an example, and a variety of system-generated names may be generated for workflow 1802 depending upon the implementation. In an embodiment, the developer can accept the system-generated name by interacting with activation button 1808 to save the workflow with the system-generated name, or may decide to alter the name. In the latter case, the developer may interact with data entry element 1806 to modify or overwrite the system-generated name before saving the workflow.

In FIG. 19, workflow designer GUI 116 displays a menu of saved workflows that a developer may interact within in order to activate, deactivate, edit, delete or perform other operations with respect to one or more of the saved workflows. As shown in FIG. 19, workflow 1802 may be represented by an icon 1902 and a name 1904, both of which may be automatically generated using the method of flowchart 1700 as described above. As further shown in FIG. 19, workflow name and icon generator 1602 may automatically generate an icon for a workflow by combining icons associated with one or more steps included in the workflow and/or services referenced or interacted with by the workflow. Thus, for example, automatically-generated icon 1902 of FIG. 19 is a combination of an icon 1906 associated with DropBox™, an icon 1910 associated with Microsoft® Outlook®, and an icon 1912 associated with Twilio®. Each of these are services referenced by workflow 1802 and thus have been combined into representative icon 1902. Furthermore, an icon 1908 has been incorporated into icon 1902 that represents the condition step within workflow 1802. However, this is only an example, and a wide variety of techniques may be used to automatically generate an icon or other graphical representation of a workflow.

E. Example Embodiments for Easily Specifying Input Parameter Values for a Workflow Step of a Workflow Under Development

As was previously described, workflow designer 106 generates workflow designer GUI 116 that enables a developer to configure a workflow step within a workflow under development, wherein such configuration includes specifying a value of an input parameter for the workflow step. In an embodiment that will now be described, workflow designer GUI 116 enables a developer to easily specify a value of an input parameter of a second workflow step to include a value of an output parameter of a first workflow step in the same workflow.

In particular, in accordance with an embodiment, workflow designer GUI 116 represents output parameters of a first workflow step of a workflow under development as user-interactive objects. These objects can be easily interacted with (e.g., clicked on or dragged and dropped) by a developer to cause the objects to be inserted into a data entry element (e.g. a text box) that is used to specify a value for an input parameter of a second workflow step of the workflow under development. When executable logic representing the first and second workflow steps is generated, the aforementioned insertion of the objects into the data entry element has the effect of causing the value of the input parameter of the second workflow step to be defined to include the values of the output parameters that correspond to the inserted objects.

This functionality will now be described in reference to FIG. 20, which depicts a flowchart 2000 of a method for defining a value of an input parameter of a second workflow step based on user interaction with one or more user-interactive objects that respectively represent one or more output parameters of a first workflow step within a workflow designer GUI, in accordance with an embodiment. The method of flowchart 2000 may be performed, for example by workflow designer 106 (or various components thereof) as previously described. For the sake of illustration, the description of flowchart 2000 will also reference FIGS. 21-23, each of which shows a different view of workflow designer GUI 116 displayed within browser window 402 of display screen 108 in an embodiment in which computing device 102 is a mobile computing device, such as a smart phone.

As shown in FIG. 20, the method of flowchart 2000 begins at step 2002, in which a user selection of a first workflow step to be included in a workflow under development is received. For example, workflow designer 106 may receive user input that indicates that a developer has selected a first workflow step “Dropbox—When a file is created.” Such input may be received via a step selection tool that is displayed within a workflow designer GUI, as was previously described, or in some other manner.

At step 2004, a graphical representation of the first workflow step is presented in a workflow designer GUI. For example, as shown in FIG. 21, workflow designer 106 may cause a graphical representation 2102 of the first workflow step “Dropbox—When a file is created” to be rendered within workflow designer GUI 116. In this example, “Dropbox—When a file is created” comprises a trigger step that monitors to determine when a file has been created in a particular Dropbox® folder. As further shown in FIG. 21, workflow designer GUI 116 includes a data entry element 2104 (in this case, a text box) and a file browser activator 2106, each of which can be used by the developer to specify or select an input parameter for this step. In particular, these mechanisms enable the developer to specify or select the name of the Dropbox® folder to be monitored for the file creation. In this example, the developer has specified the folder “Dropbox>Backup.”

At step 2006, a user selection of a second workflow step to be included in the workflow under development is received. For example, workflow designer 106 may receive user input that indicates that the developer has selected a second workflow step “Outlook—Send email.” Such input may be received via a step selection tool that is displayed within a workflow designer GUI, as was previously described, or in some other manner. With continued reference to FIG. 21, the step selection tool may be displayed when the developer interacts with an action button 2108, indicating that the developer wishes to add an action (as opposed to a condition) as the next step in the workflow under development.

At step 2008, a graphical representation of the second workflow step is presented in the workflow designer GUI. For example, as shown in FIG. 22, workflow designer 106 may cause a graphical representation 2202 of the second workflow step “Outlook—Send email” to be rendered within workflow designer GUI 116. In this example, “Outlook—Send email” comprises an action step that is carried out when a trigger event is detected by trigger step “Dropbox—When file is created.”

In further accordance with step 2008, the graphical representation of the second workflow step comprises a data entry element into which a user can input a value of an input parameter of the second workflow step. This is further illustrated in FIG. 22, in which graphical representation 2202 of second workflow step “Outlook—Send email” includes a first data entry element 2204, a second data entry element 2206, and a third data entry element 2208. The developer may interact with each of these data entry elements to specify a value of a corresponding input parameter of the second workflow step. In particular, the developer may interact with first data entry element 2204 to specify an intended recipient of an email to be sent by the second workflow step, with second data entry element 2206 to specify a subject line for the email, and with third data entry element 2208 to specify text to be included in the body of the email. In this particular example, the developer has specified (e.g., by typing text into data entry element 2204) that the value of the e-mail recipient input parameter is “msmith@domain.com”.

In step 2010, one or more user-interactive objects are presented in the workflow designer GUI that respectively represent one or more output parameters of the first workflow step. For example, as shown in FIG. 22, workflow designer 106 causes a user-interactive object 2210, a user-interactive object 2212, a user-interactive object 2214, a user-interactive object 2216 and a user-interactive object 2218 to be presented within graphical representation 2202 of the workflow step “Outlook—Send email” displayed within workflow designer GUI 116. Each of these user-interactive objects respectively represent a corresponding output parameter of the first workflow step “Dropbox—When a file is created.” In particular, user-interactive object 2210 represents a file content output parameter of the first workflow step, user-interactive object 2212 represents a file identifier output parameter of the first workflow step, user-interactive object 2214 represents a file name output parameter of the first workflow step, user-interactive object 2216 represents a file entity tag output parameter of the first workflow step, and user-interactive object 2218 represents a file path output parameter of the first workflow step.

In the example shown in FIG. 22, the developer may interact with each of user-interactive objects 2210, 2212, 2214, 2216, 2218 to cause the corresponding user-interactive object to be copied into second data entry element 2206. For example, depending upon the implementation, the developer may simply click on a user-interactive object using a mouse, touch a user-interactive object via a touch screen, or the like. As another example, the developer may drag and drop a particular user-interactive object into second data entry element 2206. Still other forms of user-interaction may be performed that will cause a user-interactive object to be copied into second data entry element 2206.

This functionality is represented in step 2012 of flowchart 2000. In particular, at step 2012, in response to user interaction with a particular user-interactive object from among the one or more user-interactive objects, the particular user-interactive object is copied into the data entry element. Thus, for example, as shown in FIG. 23, in response to the developer interacting with user-interactive object 2214 in FIG. 22 (“file name”), a user-interactive object 2302 which is a copy of user-interactive object 2214 has been included in data entry element 2206. In further accordance with this example, the developer also input some text (“was created in your Dropbox folder”) into data entry element 2206, following user-interactive object 2302.

The effect of the copying of user-interactive object 2214 into data entry element 2206 is that, at runtime, the “subject” input parameter of the second workflow step “Outlook—Send email” will be defined to include the current value of the “file name” output parameter of the first workflow step “Dropbox—When a file is created.”

For example, assume that at runtime, a file named “sales_report_0516” is created in Dropbox® folder “Dropbox>Box”, thereby triggering the trigger step “Dropbox—When a file is created”. In this case, since the “subject” input parameter of the second workflow step “Outlook—Send email” has been defined to include the current value of the “file name” output parameter of the first workflow step “Dropbox—When a file is created”, the subject of the email created by the second workflow step will be “sales_report_0516 was created in your Dropbox folder.”

This functionality is achieved by workflow designer 106 in accordance with step 2012 of flowchart 2000. In step 2012, executable workflow logic is generated corresponding to at least the first workflow step and the second workflow step, wherein the generating the executable workflow logic comprises defining the value of the input parameter of the second workflow to include a value of a particular output parameter of the first workflow step that corresponds to the particular user-interactive object that was copied into the data entry element. Thus, in further accordance with the foregoing example, workflow designer 106 generates executable workflow logic (e.g., via workflow logic generator 112 as previously described) that corresponds to at least the first workflow step “Dropbox—When a file is created” and the second workflow step “Outlook—Send email”, wherein generating such logic includes defining the value of the “subject” input parameter of the second workflow step “Outlook—Send email” to include the value of the “file name” output parameter of the first workflow step “Dropbox—When a file is created” that corresponds to user-interactive object 2214 that was copied into data entry element 2206.

FIG. 23 further illustrates how user-interactive objects 2304, 2306, 2308, 2310 and 2312, each of which represents an output parameter of first workflow step “Dropbox—When a file is created”, can be easily interacted with by a developer to insert such output parameters into the input parameter “Body” of second workflow step “Outlook—Send email.” In particular, it can be seen that the developer has interacted with user-interactive object 2308 (“file name”) and user-interactive object 2312 (“file path”), thereby causing a copy thereof (user-interactive object 2314 and user-interactive object 2316, respectively) to be inserted into data entry element 2208. At runtime, this will have the effect of including the current values of the output parameters “file name” and “file path” of first workflow step “Dropbox—When a file is created” in the value of the input parameter “Body” of second workflow step “Outlook—Send email.”

It is noted that in the foregoing description of flowchart 2000, the graphical representations of the first and second workflow steps are presented in the workflow designer GUI in response to a developer's selection of each of those steps. However, such graphical representations may be presented in response to other developer actions as well. For example, as explained elsewhere herein, graphical representations of workflow steps may also be presented within the workflow designer GUI in response to a developer selecting or loading a particular workflow template or saved workflow for editing and configuration.
